Seventy-three percent of Americans, according to a new Seton Hall Sports Poll, say they are very or somewhat concerned about attending a sporting event in a large stadium in the wake of the terrorist activity, including an attack on the Stade du France, that left at least 130 people dead.

"This is a dramatic number, and something that should be noted by all sports leagues that play in large venues," said Rick Gentile, the poll's director. "Normally Americans rally quickly and say, 'This will not change my way of life.' But in this case, it has clearly given them pause."

Twenty-three percent of the 870 Americans polled this week said the attacks made no difference on their willingness to attend a sporting event at a large stadium.
